Copyright Law

A software license agreement defines the legal framework between creator and user. It specifies permissions (what you can do), restrictions (limitations on use), and warranty terms (guarantees and disclaimers). All three components are essential.

Works or technology whose copyright has expired or never existed, making them freely available for anyone to use, are said to be in the public domain. Proprietary technology is legally restricted and owned privately.

When copyright protection expires or is waived, a work or technology enters the public domain, meaning it is free for anyone to use without restriction. Proprietary and open technologies still involve specific legal frameworks or ownership rights.

Correct option is (4).

(3) Information contained on an Internet website can be the subject of a copyright infringement claim if duplicated without permission.

Legal feasibility determines whether the proposed system conflicts with legal requirements. For e.g. copyright legislation.

The ownership of copyright is called incorporeal ownership. Ownership of a copyright is distinct from ownership of any material object in which the work is embodied. 

Perpetual access refers to the right to ongoing access to electronic materials. In situations where digital materials are licensed, access to these materials is often lost after the licensing agreement has expired. In many cases, the two parties involved in the license agree that it is necessary for the licensee to retain access to these materials after the license has lapsed. Perpetual access is a term that is used within the library community to describe the ability to retain access to electronic journals after the contractual agreement for these materials has passed.

Option 1: A book once published can be used by a reade, and notes/content may be made from the same by any reader. Drawing conclusions or notes on published material does not amount to infringement. 

Option 2: A popular TV broadcaster would never show a movie without having bought out its rights. For example, popular broadcasters viz. Star TV, ZEE Cinema can show only those movies for which they have bought the rights from respective production houses. 

Option 3: Copying content from two books and producing a new book amounts to republishing of already published material from more than one source is a clear case of "copyright infringement". 

Option 4: A cable operator has every right to show repeatedly any match/event to its subscribers just as it shows every other event, as the logo of the broadcaster is always visible to the audience. Hence, the knowledge that rights to the match lie with the specific broadcaster and not the cable operator is known to all. The cable operator merely recorded the match and replayed it for its audience.
